Abstract
Using the positron annihilation method (PA), Auger electron spectroscopy (AES), Mössbauer spectroscopy (MS), X-ray analysis and microhardness measurements, we have studied structures of P6M5 steel and A1 (99.999%) that have been exposed to carbon high power ion beams (HPIB). The modified layers formed as a result showed two sublayers: the first one of (15–20) μm had been formed due to heat transfer, the second one of (100–150) μm was due to shock waves. Dislocation loops and prisms (of vacancy or interstitial nature) were responsible for the increased microhardness. The modifications of the metals and alloys were significantly influenced by the current density.
